Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed June 27,1906. Serial No. 323,614.

To all whom it may concern:

Be it known that I, ISAAC W. SHInx, a citizen of the United States, residing at Grant, in the county of Hardin, State of Ohio, have invented certain new and useful Improvements in Axle-Adjusters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same: I

This invention has relation to a device for straightening vehicle axles or spindles, in the event of their becoming bent or sprung, without removing them from the other parts of the running gear.

It is the object of the invention to provide an entirely ei'licient contrivance for the purpose mentioned, and one that shall be simple in and economical of construction, so that it may not get out of order and become deficient in theperformance of its functions, and so that it may not be too costly for persons requiring its use to a limited extent to supply themselves with one.

The nature of the invention, as I propose to construct it, may be embodied in a machine comprising a bar that on its inner end may be caught over the axle, and that at a point toward its outer end may have a protuberance on its upper side that the underside of the axle may rest upon at a point coinciding with the accidental bend, or as near the same as can be ascertained, and means for taking over the outer end of the axle or spindle and drawing it toward the bar, so as to straighten the bend. The last mentioned means is of the essence of the invention, though not necessarily confined to the exact form and arrangement shown, since some latitude for the exercise of mechanical skill is claimed to provide for the meeting of exigencies and unusual circumstances.

In the detailed disclosure of the invention, reference is to be had to the annexed drawings, forming a part of this specification, in which:

Figure 1 is a side view of the invention, showing it as applied to a vehicle axle for the purpose of straightening it. Fig. 2 is a vertical sectional view through the end bolt.

Similar numerals of reference designate the same parts or features, as the case may be, wherever they occur.

It will be known that when an axle happens to be sprung or bent, the trouble usually occurs about the junction of the spindle with the axle proper, or in the l l I l 1 l i I l l spindle. The torsional strain upon the wheel has much to do with bringing this about but as the cause of the trouble varies, the point at which it occurs varies.

In carrying out my invention, I provide a strong bar 10 of steel, iron, or other suitable metal, having its inner end bent upwardly and hooked, as indicated by the reference numeral 11, to take over the axle. At a suitable point toward its outer end I provide the bar 10 with a suitable integral protuberance 12 on its upper side, to afford a fulcrum, upon which the axle 13 may bear at or near the point where it is bent or sprung, and in this latter expression I mean to include the spindle 14 as well as the axle, for the spindle often becomes bent or sprung, as well as the axle. It will be understood that the bar 10 is hooked at its inner end, as indicated at 11, for engagement over the axle, and at its outer end, it has a vertical opening 15 formed therethroiigh, in which there is slidably'engaged a stem 16, having an eye 17 at its upper end for engagement over the end of a spindle. .A collar 18 is engaged with the stem below the bar 10, and the stem has engaged therewith, below the collar, a sleeve 19. The stem projects below the sleeve and is threaded as shown at 20, and this threaded portion is engaged in a threaded opening 21 of the head formed in the end of a crank 22.

It will be readily understood from the drawings, that the device having been applied to the axle, as shown in Fig. 1, the crank 22 may be revolved around the stem to screw it upwardly upon the latter, which will draw the stem downwardly through the bar 10 to straighten the spindle.

What is claimed is:

An axle spindle straightener comprising, in its entirety, a bar having its inner end bent upwardly and hooked, to take over the axle, and provided with a vertical opening formed through its outer end and with an integral fulcrum protuberance located adjacent thereto; a stem slid; ably disposed in said opening and having an eye formed at its upper end for engagement with the end of the spindle; a nut provided with a crank-handle turned on the lower end of the stem; and means located between the nut and lower side of the bar. to maintain the handle in spaced re lationship to the bar, said means consisting of a collar on the stem below the bar and an elongated sleeve interme diate oi the collar and crank nut.

In testimony whereof, I affix my signature, in presence of two witnesses.

ISAAC \V. SHIRK.
